Patent DE-2352950-A1 (DE)
Title: Throughflow heat exchanger for oil or water cooling - has flat components with parallel flow channels, formed by bending light metal pressings
Inventor: WERNEKE HANS
IPC: F28F1/12
Filed: 1973-10-23
Abstract: Light metal, liquid-throughflow heat exchanger, e.g. for water or oil cooling in motor vehicles, has flat components forming flow channels, and respectively having at least two parallel flow channels the components are produced each from a plate-shaped light metal pressing by bending around the longitudinal centre and liq.-tight connection at the long edges. Preferably the components have longitudinal inner ribs which separate the flow channels and which are formed by webs on the pressed parts coming into mutual abutment. The ribs end near the ends of the components, where the channels become united. The channels have opt. cross sectional shape for heat exchange.

Title: Centring arrgmt. for a flexible shaft coupling - uses pin in end of one shaft and engages with elastomer ring in other
Inventor: STUEMKY ROBERT E
IPC: F16D3/16
Filed: 1973-11-21
Abstract: The coupling consists of an elastomer sleeve, the ends of which are bonded to metal coupling parts which can be connected to shaft ends. The coupling parts extend for some way inside the elastomer sleeve. A pin is fixed centrally in one coupling part and extends towards the other coupling part. The other coupling part is provided with a bore inside which an elastomer ring is mounted. The pin fits inside this ring. The edges of the ring are chamferred so that it makes virtually only line contact with the pin. The ring is located approximately centrally in the coupling sleeve and allows the two coupled shafts large angular misalignments. The same pin and ring arrangement can also be used with a cardan type universal coupling.

Title: Coupling between a trailer and traction vehicle - has electrical circuit for indicating trailer steering angle to the driver
Inventor: FEVRE JACOB HERMANNUS LE
IPC: B60D1/38
Filed: 1973-11-24
Abstract: The indicator sensor on the trailer coupling indicates to the driver the angle between the longitudinal axis of the vehicle and the longitudinal axis of the trailer. This angle is important to the driver on coupling the trailer to the traction vehicle. The indicator system has a nylon rope which the driver connects between the trailer and the traction vehicle. This rope is held taut and initially both vehicle parts can be in an arbitrary relative position to each other. The rope is connected to the traction vehicle rotating slider by a hook, and the slider rotates over a resistor. The resistance is varied by the relative angle and displayed to the driver. The driver is hence able to straighten his vehicle relative to the trailer for coupling purposes completely unaided.

Title: Two pressure control for windscreen washer - uses reversing impeller type pump to supply headlight nozzles also
Inventor: KOZEL FRANZ
IPC: B60S1/60
Filed: 1973-12-05
Abstract: The windscreen washer system is supplied from the same pump and reservoir as the headlamp washer system with a two pressure control and a pressure limiting valve for the headlamp washers which only opens when a set pressure is reached. The pump is an impeller type and by reversing its direction of rotation is a second pressure level is obtained. This eliminates complicated electronic controls for two pump speeds and provides a simple control. The control is linked to the light switch so that a higher pressure is automatically set with the headlights on. The system operates just as effectively with a vacuum driven washer pump, with the two pressure control obtained by opening and closing a bypass line.

Title: Small-current signalling system - has signalling source connected via push-buttons to cable supplying lamps via Zener diodes
IPC: G08C19/34
Filed: 1974-03-01
Abstract: The small-current signalling system has a signalling supply coupled to two supply lines both connected over a series of double-contact push-buttons to the transmission path cable. At the other end of the cable the signalling lamps are connected at one end to one of the cable wires and at the other via a diode and zener diode to another of the cable wires. All the zener diodes are connected to the same common wire, whilst the non-diode ends of all the lamps are connected to separate wires. Depressing any one button connects the signalling source through to the corresponding lamp and, if the voltage across the zener diode is high enough, the lamp lights.

Patent DE-2424661-A1 (DE)
Inventor: BOGAERT JAN ADRIANUS VAN DEN
IPC: G03G15/05
Filed: 1974-05-21
Abstract: 1464544 Image converter tubes AGFAGEVAERT 8 May 1974 [21 May 1973] 24168/73 Heading H1D An electron discharge image in an evacuated envelope-produced, for example, by the incidence of an X-ray, ultra-violet, visible, or infrared image, corresponding to scanned information, on a photocathode 50-is recorded as an electrostatic charge image by accelerating it through a channel electron multiplier 51 on to an electron penetrable window or windows 57 forming part of the wall of the envelope of the device; the electron image passing therethrough either forms a charge pattern directly on an electrically insulating receiving material, which is moved in synchronism with the information scanning, or produces ionization in a gaseous atmosphere separating the window or windows from the charge receiving material. The window portion of the envelope may be produced from an element formed from glass fibres containing metal cores by etching the cores away to the required thickness, and the whole window area may then be further covered with a Lenard window, e.g. of aluminium, copper, nickel, or alumina. The channel multiplier is mounted by members 60 in close proximity to the lead or uranium photocathode 50, to obviate the need for focusing elements, and may have its channels tilted at an angle of up to 10 degrees with respect to the normal to the photocathode surface, to increase multiplication. The photocathode may contact a fluorescent screen (63, Fig. 4, not shown), sensitive to an incident X- ray, gamma ray, beta ray, or neutron image. A modified arrangement (Fig. 2, not shown), for document reproduction, employs a strip photocathode, a multiplier having a single row of channels, and a single row of windows, the charge pattern being produced line-wise by progressive line-wise exposure of the photocathode with visible light.

Title: Snap on cover for equipment containers - cover has inserted latch that pivots during location until dead centre is passed
Inventor: SIEDENBURG BERND
IPC: F16B5/06
Filed: 1974-06-12
Abstract: A snap on cover locates on a fixed rail attached to an equipment container e.g. electrical switchgear housings. A fixed rail (3) mounted on the housing (5) has a top edge (4) that provides initial location for a recessed lip in the cover (1). The bottom of the cover is profiled to accept a separate latch (10) that pivots in a slot. When the cover is initially located on the top edge of the rail (4), the latch is brought into contact with the bottom edge (11.2). As the bottom edge of the cover is pressed nearer to the housing the centre line (20) between the top pivot point (4) and the latch pivot moves nearer to the fixed line between the rail projections (21).

Title: Switching points for levitated railway system - uses asynchronous stator elements for short period power supply
Inventor: WEH HERBERT PROF DR ING
IPC: B60L13/03
Filed: 1974-07-29
Abstract: The noncontacting switching points are used in a railway with levitated track, and have no moving parts.

Title: Adapter for telescope to observe solar protuberances - has housing with connection to the telescope eyepiece
Inventor: EVERETT GEORGE
IPC: G02B23/16
Filed: 1974-09-17
Abstract: A dimming device inside the housing is supported in a plane and on the longitudinal axis of the housing to dim an image in this plane. Facilities on the longitudinal axis inside the housing focus the dimmed image in another plane, so that the dimmed image can be seen in the second plane by means of an eyepiece connected to the adapter.
